Yeah, my example stank, but I do know the difference between DOMS and strength

. I got DOMS because I was working muscles differently than I usually do.
Yes, it will be a benefit. Is lifting heavy the best way for everyone? I don't necessarily think so. Is it effective? Yes of course.
The posts I was responding to dealt with, how they phrased it, "gym strength" vs "core strength" through different methods and that they do not necessarily have to be same but I clearly buggered that up.
What I was trying to get at, is that the way you train is going to give you strength in different scenarios/applications and I don't think that it is necessarily just technique related. For example take a noob guy who trains his back with deadlifts and rows versus another noob guy who trains bridging. Put both of them in a Kesa gatame and see which one has a harder time getting out. I would venture the weight lifting guy. Pick another scenario and the weightlifter would do better because the way he has trained will be more applicable to that situation.
And I completely agree that if two people start training at the same time the one who is stronger will have the advantage in the long run. But I do not agree with heavy lifting being the end-all-be-all.
And then of course I could be wrong about all of that
